1 (8 oz.) pkg. refrigerated crescent dinner rolls
1 (4 oz.) pkg. sliced cooked ham
1/2 (8 oz.) pkg. sliced Swiss cheese
2 tsp. prepared mustard
1 egg, slightly beaten

On floured surface, separate dough from the crescent dinner rolls into 4 rectangles. Gently pinch diagonal perforations together on each rectangle. Roll each rectangle in 5 x 7 inch rectangle. Arrange ham and cheese slices on dough rectangles, cutting ham and cheese to fit and leaving 1/2 inch rim of dough all around.

Spread filling with mustard. Brush rim of dough with egg. Fold dough and filling over so 5 inch sides meet. With fork, firmly press edges together to seal. Place on cookie sheet; brush with remaining egg. Bake at 375 degrees for 12-15 minutes.
